' The present invention is directed to improvements in cooling apparatus.

' The primary object of the invention is to provide a device of this character especially 5 adaptedfor maintaining meat or other per-1 ishable commodities in a cool state by efif cient circulation of chilled air.

Another object of the invention is to pro or other enclosure.

Another object of the invention is to provide an apparatus of this character which is portable and capable of being readily in-I stalled, the construction being such that the circulation of air 'willbe positive without" '20 the aid of fans.

tion of which is such that pipe coils are eliminated vand consequently the objection able frosting and rusting thereof s dlspensed' with With these and other objects 111' view, this invention resides in the novel features of con 1 struction, formatlon, combination andar rangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawings, in which,

A drain valve 25 is connected with the tank in order that sediment can be drawn there- One side of the chamber 1 is provided with a door opening 26 which is normally closed by a glass paneled door 27, said door being for the purpose of permitting inspection of the chamber and owing to the glass panels thereof the condition of the spray can be readily observed, there being an incandescent bulb 28 located in the dome in order thatthe 7 interior of the chamber will be illuminated when necessary.

It will be observed that the pipe assemblies 7 16 contain ten spray nozzles, whereas the pipe assemblies 20 include twenty spray nozzles, thus the pump for use in connection with the latter sprays will be one having a greater pressure rate than the one for pumping the By providing the shutters 12 it will be obvious that the passage of particles of brine in r the air passing therethrough will be impededso that as the air enters the neck 7 it will be in a comparatively dry state for efficient c001 ing purposes.
